Innovative Strategies For Risk Reduction Following CABG
Background: Treatment targets for cardiac risk factor reduction are not being met. Therefore, there is a need for new strategies to assist patients in meeting these goals.
Objective: To determine the amount of any additional benefit on risk factor reduction associated with the consumption of the "dietary portfolio" (a low fat diet with soy, nuts and viscous fibres), above that achieved with medical management in diabetic patients following cardiac surgery.
Description: 35 cardiac surgery patients with diabetes will be instructed on how to incorporate the dietary portfolio foods into their diet for four weeks. Changes in blood cholesterol, markers of inflammation, blood sugar control and modifiable risk factors will be assessed after 2 and 4 weeks of therapy.
Relevance: Maximizing cardiac risk factor reduction through a combined approach (dietary plus medication) should improve outcomes, reduce rates of re-hospitalization and improve quality of life in diabetic patients after heart surgery.
